post_type => array stopped working in 3.5.2

I have a query that grabs from posts various post types have a certain category. It worked in 3.5.1, but no more.
Now it just returns posts for the last post type listed.
Can anyone offer any guidance?

global $post;
                  $args = array( 'numberposts' => 5, 'post_type' => array('press','news','tribe_events'), 'category' => '9' );
                  $myposts = get_posts( $args );
                  foreach( $myposts as $post ) :   setup_postdata($post);
